THE SNAKE BUZZARD.

[Illustration: THE SNAKE BUZZARD (_Circaëtus brachydactylus_, or

_Circaëtus Gallicus_).]

The SNAKE BUZZARD (_Circaëtus brachydactylus_, or _Circaëtus Gallicus_)

is from twenty-six to twenty-eight inches long, and from sixty-six to

sixty-eight across the wings; the latter measure eighteen, and the tail

nine inches. The upper part of the body of this bird is brown, the

feathers upon the head and nape pale brown, tipped with a still lighter

shade; the quills are blackish brown, edged with two borders, one being

white, the other pale brown, and marked with an irregular black line; the

tail is brown, broadly tipped with white, and adorned with three black

stripes; the brow, throat, and cheeks are whitish, and streaked with

delicate brown lines; the crop and upper part of the breast are bright

light brown; the rest of the under part of the body is white, with a few

brown spots. The large eyes are surmounted with a ring of wool-like down,

and the cheek-stripes are covered with bristles; the eye is yellow, the

beak blueish black, and the cere and feet light blue. The young differ

but slightly from the adult birds.

Until the beginning of the present century this Buzzard was almost

entirely unknown, but it is now met with throughout all the countries of

Southern Europe. Its habitat, however, extends beyond that continent;

indeed, it often wanders far into Northern Africa, and Jerdon mentions

it as common in India. In Central Europe it is a summer bird, appearing

about May, and departing early in the autumn; its disposition is

extremely quiet and indolent, and as it usually prefers to seek shelter

in the recesses of forests, is not very frequently seen; in Hindostan,

on the contrary (where it breeds), it inhabits the more open country,

whether the latter be dry or marshy. In Northern Africa it flies about

during the winter in parties of from six to twelve, often settling on

such rocks as are near rivers, but more generally upon the open and

barren steppes; it has also been known to breed in North-western Africa.

The Snake Buzzards, according to our own experience, although quiet and

idle, are exceedingly quarrelsome while occupied with the care of their

young; at other times they are remarkably timid, and often utter loud

cries if disturbed. Those we saw in Africa would remain perched when we

approached, and glower at us with their large eyes in a most unearthly

manner, without attempting to save themselves by flight. It is only early

in the morning and late in the evening that they are seen upon trees,

the entire day being spent in searching after prey. While thus employed

nothing can exceed the deliberation with which they move; indeed, it

would be difficult to find in any other members of the feathered race

such a picture of indolence as they present, while they sit motionless

at the edge of the water, or flap their way ponderously through the air.

Towards its own kind this bird exhibits many most unamiable qualities,

for so greedy and envious is it, that should one of its brethren prove

fortunate in the chase, a hard-fought battle is sure to ensue, in order

to compel the possessor of the coveted morsel ignominiously to resign its

prize, and during such encounters the combatants often use their claws

with so much effect that, powerless to fly, both fall together to the

ground. About noon the Snake Buzzard appears upon the river banks, over

which it hops much after the fashion of the Raven. An isolated tree is

usually selected for a sleeping-place, as from such a situation the bird

can command a view of the surrounding country.

The food of this species consists principally of reptiles, though it also

devours large quantities of fish, which, should the water be shallow,

it readily obtains; according to Jerdon, it also consumes rats, small

birds, crabs, and the larger kinds of insects. The manner in which

this bird gives battle to serpents has been thus described: "A young

individual in my possession," says Mecklenburg, "would dart down upon

any snake, however large or fierce, and after seizing it with its claws

behind the head, bite it vigorously several times through the nape; the

reptile, thus paralysed, was then swallowed by degrees, commencing with

the head, each new mouthful being prepared by a preliminary bite through

the backbone. During one forenoon I have seen my bird kill and devour no

fewer than three large snakes, one of which measured nearly three feet,

and was very thick. I have never known an instance in which it tore its

prey to pieces before swallowing it. The scales were usually cast up

again undigested." Elliot mentions having seen one of these Buzzards

completely enveloped in the folds of a huge poisonous snake, the head

of which, however, was held so firmly in the bird's beak, that all its

efforts to free itself were fruitless. The thick coat of feathers in

which this species is enveloped is its only protection against the deadly

fangs of its victims; recent experiments have proved that its system is

not, as was once supposed, proof against their poison.

The eyrie of the Snake Buzzard is built about June; it is flat in shape,

and formed of branches and twigs; the interior is lined with green

leaves, and green branches are also fastened outside to protect the

little family from the rays of the sun. It is not uncommon for a pair of

these birds to return year after year to the same eyrie. They lay one or

two eggs of an oval shape, with very thin, coarse shells, of a blueish

white colour. Both parents participate in the labour of incubation,

sitting alternately upon the eggs for about twenty-eight days. We are

told, on reliable authority, that, if molested, the mother bird removes

her young to another place. The Snake Buzzard is easily tamed if taken

early from the nest.

The CRESTED BUZZARDS (_Spilornis_) are a group of very remarkable birds,

inhabiting the most southern countries of Asia and Africa. Such species

as we are acquainted with are of considerable size, and powerfully built;

their pointed wings, in which the fourth quill is the longest, extend to

the middle of the tail; the latter is of moderate length, and rounded at

the extremity; the tarsus is high, and the talons short and sharp; the

beak, which is straight at the base, curves abruptly towards its tip; the

margin of the upper mandible is without teeth, whilst that of the lower

one is excised near the extremity. The plumage is thick, and prolonged

into a crest at the back of the head.
